2. The occupation by a submerged body or part of a body of a volume which would otherwise be occupied by a fluid.

The resistance of the thin wire is greater than the resistance of the thick wire because the thin wire has fewer electrons to carry the current. Therefore, for thinner pieces of conducting putty we have the larger resistance and for the thicker pieces of conducting putty we have the lower resistance.

Explanation:

BeCl2 referred to as Beryllium Chloride, is an inorganic compound. It appears as white or yellow crystal solid at room temperature. It can exist in both monomeric and 1-D polymeric forms. The properties of beryllium chloride are similar to aluminum chloride owing to the diagonal relationship of beryllium with aluminum.

The molar mass and melting point of beryllium chloride are 79.91 g/mol and 399 °C, respectively. The chemical bonding in Beryllium Chloride is studied by writing down its Lewis structure by following the Lewis approach.

After lewis structure, there is a need of understanding its molecular geometry and hybridization of the central atom, Beryllium. The molecular orbital (MO) theory will be used to understand the MO diagram of beryllium chloride.

Beryllium Chloride

[tex]{ \boxed{ \mathfrak{formula : \: { \rm{BeCl _{2} }}}}}[/tex]

Beryllium chloride is formed through ionic / electro-valent bonding. The beryllium atom loses its two valency electrons to the two chlorine atoms each with seven outermost electrons.

As a result, an ionic compound Beryllium chloride is formed.

Boron Fluoride (BF3)

Boron trifluoride is formed through interaction of π bonds with the double alpha bonds of fluorine.

From VESPR, the structure is tetrahedral and non-symmetrical hence polarity is high.

Since, fluorine is highly electronegative, it makes the bond polar

All in all, Boron Fluoride is formed through hybridization.

Ammonia (NH3)

Ammonia is formed through hydrogen bonding.

Hydrogen bonding is a covalent bonding situation where hydrogen bonds with a highly electronegative element such as oxygen, fluorine, nitrogen.

Explanation:

Using the facts

Ectoparasites are a taxonomically diverse group of organisms that infest the skin of human beings and other animals. Ectoparasitic arthropods and nematodes are similar in that an individual organism can produce skin lesions that are large enough to see with the unaided eye. Ectoparasitic infestations are often intensely itchy, causing considerable annoyance and discomfort. These conditions are often focally hyperendemic in impoverished communities, with a particularly high prevalence in vulnerable families, households, and neighborhoods.

Pediculosis (infestation by head and body lice) and scabies are found to some degree in all human populations, but myiasis (fly larva infestation), tungiasis (sand flea disease), and cutaneous larva migrans occur mainly in tropical and subtropical environments. Except for body lice, the organisms discussed in this article are not vectors of pathogenic microorganisms. In other words, most ectoparasites do not carry disease-causing agents; they are, instead, the direct cause of disease. Mortality is low, but the cumulative morbidity from the direct discomfort, secondary bacterial infections, and sequelae of those infestations and infections is considerable.

Despite the abundant presence of ectoparasitic infestations across human populations, biomedical science lacks firm evidence-based practices to reliably control these organisms. In addition, head lice and scabies are developing resistance to some chemical compounds employed to treat infested individuals, prevent spread, and control outbreaks.

Dada la información de la pregunta, el calor absorbido por el cobre es de 12513 J o 2990 calorías.

El calor ganado se obtiene de la relación;

H = mcdt

Dónde;

H = calor absorbido

m = masa

c = capacidad calorífica del cobre

Δt = cambio de temperatura

La capacidad calorífica del cobre es de 385 J / kg / ° C

Entonces;

m = 250 gramos o 0,25 kg

Δt = 150 ° C - 20 ˚C = 130 ˚C

H = 0,25 kg * 385 J / kg / ° C * 130 ˚C

H = 12513 J o 2990 calorías

The given kinematic equations of motion are derived from Newton's Laws

of Motion.

Reasons:

The direction the ball is kicked = Upwards in the air

Maximum height to which the ball rises = 6.25 m

A) The speed of the ball the instant it left the soccer player's foot

Solution:

The equation to use is; v² = v₀² + 2·[tex]a_y[/tex]·(y - y₀)

[tex]a_y[/tex] = The acceleration due to gravity ≈ -9.81 m/s²

At the maximum height, y - y₀ = 6.25 m

The velocity at the maximum height, v = 0

v₀ = The speed of the ball the instant it left the soccer player's foot

Which gives;

v² = v₀² + 2·[tex]a_y[/tex]·(y - y₀)

0 = v₀² - 2 × 9.81 × (6.25) = v₀² - 122.625

v₀² = 122.625

v₀ = √(122.625) ≈ 11.074

The ball's speed the instant it left the soccer player's foot, v₀ ≈ 11.074 m/s.

B) Required:

The time it takes the soccer ball to rise to the maximum height.

Solution:

The equation of motion required is v = v₀ + [tex]a_y[/tex]·t

At the maximum height, v = 0

v₀ ≈ 11.074 m/s

v = v₀ + [tex]a_y[/tex]·t

Which gives;

0 = 11.074 - 9.81 × t

[tex]t \approx \dfrac{11.074}{9.81} \approx 1.129[/tex]

The time it took the ball to rise to its maximum height, t ≈ 1.129 seconds

Answer: add it

Explanation:

The magnitude of the magnetic field B(r) inside the capacitor as a function of distance from the axis is [tex]\mathbf{B(r) =\dfrac{\mu_o I r}{2 \pi a^2} }[/tex]

A charged capacitor usually cause changes between the plates of electric field E and the electric flux Φ

As seen in Ampere's law which is extended by Maxwell:

[tex]\mathbf{\oint B^{\to} .dl^{\to} = \mu_o \Big( I+\dfrac{d \phi }{dt} \Big)}[/tex]

To meet the equilibrium equation of electric charge, Maxwell modified Ampere's law by incorporating the displacement current through into electric current component.

∴

The displacement current can be expressed by the relation;

[tex]\mathbf{I = \varepsilon_o \dfrac{dE}{dt} }[/tex]

From the given information, the displacement current density through area A can now be expressed as:

[tex]\mathbf{I = \varepsilon_o A \dfrac{dE}{dt} }[/tex]

Replacing the value of displacement current density into Maxwell modified Ampere Law, we have:

[tex]\mathbf{\oint B .dl= \mu_o I_{enclosed} }[/tex]

[tex]\mathbf{B \times (2 \pi r) = \mu_o I\Big (\dfrac{\pi r^2}{\pi a^2} \Big) }[/tex]

[tex]\mathbf{B(r) =\dfrac{\mu_o I r}{2 \pi a^2} }[/tex]

Answer:

Fc= 47.363 N

Explanation:

First, you need tangential velocity because they don't give that to you in the problem.

So, the formula for tangential velocity is υ=2πr/t.

For this problem its v=2π4/10= 2.513 m/s

Then we plug this into our equation for centripetal force

Fc= 30*(2.513)^2/4=47.363 N

Fc=47.363 N

The centripetal force acting on Tommy is 47.36 N if Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.

A tangible body's mass is the amount of matter it possesses. It's also a metric of inertia or the resistance to velocity when a net force is exerted.

It is given that:

Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.

As we know the formula for the centripetal force:

Fc = mv²/r

m = 30 kg

r = 4 meters

First, find the tangential velocity:

The formula for tangential velocity is:

v = 2πr/t

v = 2π4/10

v = 2.513 m/s

Plug the values in the formula:

Fc= 30(2.513)²/4

Fc = 47.36 N

Thus, the centripetal force acting on Tommy is 47.36 N if Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.
